The following table describes the ports on the panels.
3.1.1 Ethernet Ports
The GS1510-16 has 16 auto-negotiating, auto-crossover RJ-45 Gigabit Ethernet
ports.
The GS1510-24 has 24 auto-negotiating, auto-crossover RJ-45 Gigabit Ethernet
ports.
The speed of the Gigabit Ethernet ports can be 10 Mbps, 100Mbps or 1000Mbps
and the duplex mode can be half duplex (at 100 Mbps) or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(100/1000Mpbs) and duplex mode (full duplex or half duplex) of the connected
device.7
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-
through or crossover Ethernet cable.
3.1.1.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
3.1.2 Mini-GBIC Slots
There are two mini-GBIC (Gigabit Interface Converter) slots for mini-GBIC
transceivers on GS1510-24. A transceiver is a single unit that houses a
transmitter and a receiver. The Switch does not come with transceivers. You must
use transceivers that comply with the SFP Transceiver MultiSource Agreement
(MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
